FIRING- MEOHANISM FOR GUNS.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed June 29, 1909. Serial No. 504,966.

To all whom it may concem:

Be it' known that I, CHARLES GREEN, of Syracuse, in the countyofOnondaga and State of New York, have invented a certain new and usefulFiring Mechanism for Guns,

'of which the following is a specification.

My invention has for its object the production of a particularly simpleand efiicient firing mechanism for guns and it consists in thecombinations and constructions hereinafter set forth and claimed. i

In describing thisinvention reference is had to the accompanyingdrawings in which likecharacters designate corresponding parts in allthe views.

Figures 1 and 2 are elevations of the frame of a gun, showing parts ofthe firing mechanism indifi'erent positions and the triggers as lockedtogether. Fig fl is a detached view' showing the triggers when notlocked together. Figs. at, 5 and 61 are views of parts seen in- Fig. 3,one trigger being removed, showing, respectively, the positions of theparts of the single triggg mechanism before the first firing,immediately after the first firing, and before the second firing. Fig. 7is a plan of parts seen in Fig. 3.

v Fig. 8 is an inverted plan, partly broken away and partly in section,of the trigger plate and triggers.

1 is the frame; 72 and ,3 are, respectively,

- the hammers and one of the main springs;

and 4 and 5 the sears'and sear springs of a double barrel gun, all ofwhich parts may be of desirable form,"size, and construction.

6 and 7 are-left and right triggers, the upper portionso'r blades 8 and9 of which are movable between front and rear posts 10 and 11 spacedapart on the detachable trigger plate 12 of the frame, said triggersbeing pivoted, respectively, at 13 and 14- to the front post 10.Saidfront post 10 is preferably formed with vertical slots or grooves 15in which the front ends of the trigger blades 8' and ,9 extend, and thepivot 13 and upper edge or face of the trigger :blade 8 are locatedbelow the pivot 14: and

the upper edge or face of the trigger blade 9. The trigger blade :9 ofthe trigger 7 acts directly uponthe corresponding or'right' and thepivot 17 thereof being alined with the pivot 14 of the right trigger 7and being usually integral therewith. This firing element or plate 16 isprovided with a surface 18 of suflic'ient width to trip either of thesears l, and is also provided with a selector 19 having a part movablelaterally thereon and formed with a surface 20 arranged above thesurface 18. The selector can be shifted to trip either the right or leftsear first, the surface 18 of the, firing plate effecting the secondfiring. The selector 19 is pivoted by a vertical pivot 21 on the up-- 4per side of the firing element or plate 16 and is shifted as hereinafterdescribed. The firing element 16 and selector 19 constitute partsassociated with the trigger 6 and arranged in different planes toefiectsuccessive firing.

22 is a member for'controlling the second firing and preventingdoubling.when the.

trigger 6 is used to trip either sear, or when the trlgger 7 isconnected to the trigger 6 as hereinafter explained. Said of the firingplate 16 and located between said firing plate 16 and the trigger blade9 of the trigger 7 is shiftable forwardly. and rearwardly relative tothe firing plate 16, and is also movable with said plate, and saidmember 22 is normally held from forward controlling member isslidablymounted'on the side face movement during the first pull of thetrigger 6 (or 7 when the triggers arej'con--- nected), and the upwardmovement thereof with the firing plate 16 during the first pull of thetrigger 6 or 7 is limite As here shown the controlling member is movedforwardly by a spring 23, and is provided with a forwardly-facingshoulder 24 which cooperates with a laterally projecting catch orshoulder25 provided on the firing plate 16. Said member 22 is-alsoprovided with an angularly-faced shoulder 26 coact ingwith a fixed stopor shoulder 27 on the rear post 11, and'with a downw'ardly'andrearwardly inclined cam face 28 cotiperating with means as a pin 29 onthe rear post 11".

The angularly-faced shoulder 26 faces upwardly and is provided with ahorizontal face 30,- and with an upwardly and rearwardly inclined orbeveledface 31 located in rear of and meeting the horizontal face, the

inclined face 31 eoacting with a beveled face 32 on said fixed stop 27.

The controlling member 22 is guided in its movement by pins 33 arrangedon the firing eh-nnent and engaging horizontal surfaces of thecontrolling member 22, the rear pin 33 being slightly spaced apartfromthe horizontal surface of the cont-rolling member coacting therewith.During the first pull of the trigger 6, the upper face of the selectorcf cts the tripping of one sear, and during the movement of mirdlydacingshoulder 26 encounters the listed stop 2], preventing further upwardmovement of the controlling 'member with the iii-lug element, but saidfiring element is free to continue its upward movement relatively to thecoijitrolling member for a limited distance until the rear pin 33thereon engages the controlling member and prevents further movement ofthe firing element relatively to the controlling member. The movement ofthe firing element relativcl-y to the controlling member carries thecatch on the firing element 16 upwardly, out of engagement with theforwardly-facshoulder 24 of the controlling member .u-I-z, 5, leavingsaid member 22 free to be impelled forwardly by its spring 23. But, asseen in Fig. 5, said forward movement is regulated and retarded byreason of the engagen'ient of the inclined face 31 of theupwardly-facing shoulder 26 with the beveled face 32 of the fixedstep27, so that the continued pull of the trigger, taking placev beforethe involuntary pull, will be of no effect. Upon the release of thetrigger after the involuntary pull the spring 23 moves the controllingmember forwardly withdrawing the upwardly facin shoulder 26 from undersaid fixed stop 2:, Fig, 6, and thus permitting the firing element 16 tobe moved further upward to-bring the surface 18 of the firing elementinto engagement with the 'other'seiar. During the cocking of thehammers, by the breaking of the gun, the sears 4 and firingplate 16 aredepressed in the usual manner forcing the cam face 28 into engagementwith the pin 29 on the rear post.

11, said cam face 28 forcing the. controlling member 22, backwardlyuntil the upwardlyfacing shoulder 26 thereof is under the fixed stop 27,Fig. 1. As thecontrolling member reaches the limit of itsbackwardmovement,

the spring 23'rocks said member on the front pin 33 as a pivot in adirection at an angle to the firing element, the updepressed or movedforwardly on its pivot 14 from its position shown in Fig. 3, to thatshown in Fig. 1, so that its upper edge is out of position toengage theright hand sear. Thetriggers are locked together by means of a pivotedcatch 34, Fig. 8, on the left hand trigger 6, which engages a pin orshoulder 35 on the right hand trigger 7, so that the triggers move as aunit when either one is pulled.- The firing plate 16 is moved by theright trigger 7 through the medium of the left trigger 6, and, saidtrigger 7 being depressed out of its normal position, will not actdirectly upon the right sear, but the firing-will be effected by thefiring plate 16 and selector 19.

As seen in Figs. 1 and 2,-the means for preventing doubling or firing bythe involuntary pull following the first discharge acts directl on thesears and is here shown 35 as indepen ently swinging weights 36 pivotedat 37 to the upper tang 38 of the gun and normally arranged out of the,path of the endsiof the sears and being free to swing rearwardly againstthe action of a weak spring over the rear ends of the sears, Fig. 2. Theweights are held from swing- ,ing forwardly from their normal positionsby shoulders 40 on the upper tang 38. After one sear has been trippedthe corresponding weight 36 is held from swinging backwardly by thetripped sear. Fig. 2.

A safety device ,is provided for locking the triggers from movement,said safety de; y vice being here shown as a slide 41 movable along thelower face of the upper tang 38 and having aj-finger-piece 42 arrangedon the outer face of said upper tang 38 and connected to the slidethrough a slot 43, the slide 41 also having a downwardly-extending arm44 which engages upwardly-ex tending arms 45 on' the triggers 6 and 7.This arm 44 is formed with a l-extensional; located between front andrear laterallyextending arms 47 an'd48, provided on the selector-19.When the slide 41 is in itscentral position the arm 44 is directly overthe arms 45 on the triggers for preventing move ment of the triggers.Whenthe slide 41 is shifted to'its forward position theex'tension 46engages the front arm 47 of the selector; shifting the selector to theright, and when the slideis shifted to its rear position said extensionengages the rear arm 48, shifting the selector to, the left. Theswinging weights 36 also act asa safety device for preventing accidentalfiring, when by, falling or otherwise the butt of the gun strikestheground, as the force 'of the impact swings said weights 36 rearwardlyover the ends of the sears.

By my invention either trigger can be used singl one to operate theright sear and the oter the left, or either-trig er can i form part oftlie's'ingle trigger mec anisrn 7 may be dispensed with if desired.
